 Polyacrylamide can be used by selecting different molecular weights according to different purposes and user requirements on product performance.

1)Sludge Dewatering: As a flocculating agent, mainly used in industrial solid-liquid separation process, including settlement, to clarify,concentrate and sludge dewatering processes, applications for all the major sectors are: urban sewage treatment,paper,food processing, petrochemical, metallurgical, processing, dyeing and the sugar and all kinds of industrial wastewater treatment.

The product has special good effect to suspended matter in organic colloidal state and can accelerate dehydration and filtration of sludge rapidly. The relevant type can be chose based on the character of sludge, and the product will not stick to filter cloth during dehydration and will not loosen when filter pressing with a high efficiency.

 2)Treatment of Sewage Water and Organic Waste Water: the product shows electropositivity in acid or alkaline media, thereby the product is extremely effective for flocculation, sedimentation and disambiguition of sewage water whose suspended particulates are provided with negative charge such as waste water of alcohol plant, waste water of brewhouse, waste water gourmet powder factory, waste water of sugar making plant, waste water of manufactured meat plant, waste water of beverage factory, waste water of tectile and printing & dyeing mill, dyeing wastewater, leather wastewater, oily wastewater treatment, and the like. The effect of using cationic-polyacrylamide is several times or dozens of times better than using anionic-polyacrylamide, nonionic- polyacrylamide or inorganic salt since the waste water is generally provided with negative charge.

3)Paper making auxitliary: In the paper industry can be used as dry strength agents, retention agents,filter aids,can be greatly improved as paper quality, enhance the physical strength of paper and reduce the loss of fiber or filler to accelerate the treatment, since enhanced retention to help filter effect can also be used in the treatment of white water at the same time, in the drinking process can play a significant flocculation.

4) Fiber cement (asbestos - cement products) will enable the forming of asbestos - cement products improved drainage; insulation board in, and fiber additives can increase the binding capacity.

3.Storage Condition:

PAM can be stored for more than two years in a dry and cold place, but the storage time is limited after PAM is mixed into solution. Should avoid contact solution and iron ion when preparing, transferring and storing PMA solution, and equipment for preparing polymerization solution is preferably made from carbon steel with stainless steel, glass fiber reinforced plastics or plastic linings.
